Features
Modular & unconstrainted design system
The behaviour of every entity (sprites, backgrounds, obstacles, ...) even invisible (timer, AI, ...) and their influences each to other are modeled as totally independant and reusable Objects and Interactions. As a result, types of objects are not limited. The only limit is your imagination and your computer power.
Physics modeling
Everything is math! That means taht objects or interactions properties will all be specified using mathematic formulas and then maybe real physics formulas, if your goal is to design simulations.
Powerful collision detection engine
Nerma2D gives you convenient mechanisms to change the quality/performance of each collision mask and even its shape. The Collision Layer concept allows you to use many collision masks at once giving the ability to design more complex objects behaviours.
